In adherence with global demands and the high standards set down by the industry, TechnoBend provides a comprehensive in-house testing facilities to identify any hidden indication of potential flaws in conjunction with the applicable specifications. Tensile test sample also known as Tensile Bolt in which it will be pulled until the sample break. Bend testing is a procedure to determine the relative ductility of metal that is to be formed usually sheet, strip, plate or wire or to determine soundness and toughness of metal after welding, etc. The specimen is usually bent over a specified diameter mandrel. Hardness test The ability for the sample to resist indentation determines hardness. Hardness may be defined as the resistance to permanent indentation.
